Bobstay rigging

Postby erbster » Sun Sep 09, 2012 9:02 pm

Hi folks,

Had my CC on the water for a week over the Bank Hol and I feel that I am getting to grips with things. As a trailer sailor, I am looking for ways to make rigging/derigging as easy as possible.

I have been looking at the bobstays (in the interest of clarity- ie in case this is the wrong term -the metal wires from the hulll to the end of the bowsprit) on my boat are attached to bottle screws, which are in turn attached to the boat with several turns of what I expect is dyneema.

I have two issues with this: 1) not easy to attach and detach (although I tend to leave these attached when trailing) and 2) it doesnt look very neat- wouldnt it make more sense for the bottle screw to attach either directly to the boat or via a shackle. To do this would need longer (larger diameter) bottle screws.

What arrangements do others have? I have looked at the pictures people have put up but cannot see enough detail to work out how others rig it.

Thanks

Charles

Bobstay

Hi Charles,

I have uploaded a picture of my solution, which works well and is quickly rigged and derigged. See

Hello Charles

You are correct, it is the wrong term. For some reason on a Capecutter the bobstay is called a waterstay and the bowsprit shrouds are called bobstays.:(

I use the same method as Frank on Katrina. i.e. a small snapshackle lashed to the end of the bowsprit shouds (bobstays in CC19 speak!). Frank has a good photo of the arrangement in his Katrina album. It is very easy to attach/detach with just enough tension on the lashings (which I find never need adjusting).

Frank has chosen bronze for his fittings, mine are cheap and cheerful stainless steel.

I have also posted in "Mary Ann Modifications" album a photo showing the position of the outhaul jamming cleat which you were asking about. I have since noticed that there is a good photo in the Katrina album showing the same arrangement.

I hope this helps.
Cheers

Dennis

Zimp has only a lashing, see my album.
Easy to adjust and no rattling when you lifted the bowsprit.

Thanks for that. This is exactly what I had in mind, except the the wires are far too short for this arrangement! This suggests that the wires are not the same length on different boats?

It certainly does, Dennis.

I have something not too different, except that I have string AND a bottle screw. I thought it would look nicer if it was "all metal". Maybe I just need to tie it up a bit neater...

That main outhaul arrangement looks very straightforward. What dia rope is that- guessing 6-8mm?

Thanks for the hints. Might even be able to rig up the outhaul before the weekend...

..


Hello Charles

It is 4mm dia.

It is the rope supplied by HM when I bought the boat.

Quick Release Bobstay Rigging

Postby David Peck » Tue Sep 11, 2012 2:32 pm

Bobstay Rigging

Because I always fold my bowsprit back when entering my marina (or any other marina – it ensures easier manoeuvrability in tight spots), I use a quick release system employing stainless steel pelican snap shackles with adjustable bottle screws. Once set to length the system tensions the bobstay wires when the pelican hooks are closed. The system is shown in my photo albums (see links below).

The right angled (twisted) shackles are to ensure a vertical pull can be applied to release the pelican hooks under tension.

Mine are connected with 4mm rope; the one side is fixed and connects with a small shackle, and the other has a shackle on the hull eye and I pass the 4mm through a few times before cranking up some tension and adding a few half hitches.

I'm spending more time trying to make Zephyr faster to rig/de-rig, so I could use a snap shackle I suppose. Since I now leave the shrouds connected my current thoughts are around making the forestay easier to fit. I hate the toggle thing, with it's fiddly clevis pin, so I'm trying to see if I could use a snap shackle or one of the pelican ones in David's pictures. In short, if it's fiddly and needs a tool it has to be replaced. The kicker now stays connected to the tabernacle, with only a 316 carbine hook to clip onto the boom loop.

I'll have rigging down to 45 minutes soon. :D

Snap shackles certainly speed things up.
As well as the bowsprit shrouds I use them on the head and the tack of my (hanked on) staysail.

I like the idea Russell, regarding the use of a snapshackle on the forestay. Unfortunately this would not work on Mary Ann. With the forestay tensioned I have not much adjustment left on the bottle screw. I would have to change something to make the forestay shorter by at least the length of the snapshackle. (I seem to remember that forestay length being discussed previously on this forum!)

When you find a solution please let us know about it.
Cheers
